' A iplica'tion filed November 13, 1911. Serial No. 6591943.

To all whom it may concern: machine is provided. The fine material that Be it known that I, Trmooon VVILLMA, a finds its way through the screen 22 falls into citizen of the United States, and resident a'receptacle 2i and is mingled with water of Milwaukee, in the county of Milwaukee admitted to said receptacle through a feedand State of Wisconsin, have invented cerpipe 25 to form a semi-liquid substance or thereof.

tain new and useful Improvements in Sepamud that escapes through a nozzle 25 of raters; and I do hereby declare that the folthe aforesaid'receptacle onto an inclined dislowing is a full, clear, and exact description tributer plate 20, that in turn discharges onto the first of a series of pivotally coupled -My invention consists in what is herein shaking-tables 27, 27 on different planes particularly set forth with referenceto the and arranged to feed one to another, these accompanying drawings and pointed out in tables being preferably spirally grooved to the claims of this specification, its object betrap mineral from which other material has ing to provide simple, economical and eiiibeen washed away, said grooving being cient means for hydraulic separation of minhereinafter more particularly specified. The

The vember 14, 1911, No. 1,009,004. outermost shaking-table 27 discharges into Figure 1 of the drawings represents a con lpartments of a preferably partitioned plan view partly in section of a separator settling-box 28 having overflow-spouts 28' machine comprising means in accordance that empty into a lead-off trough 29, mineral with my invention for the hydraulic sepaparticles being trapped in said settling-box 0 ration of minerals from other material from which the lighter material is washed crushed therewith; Fig. 2, a sectional view away by water fed to said tables from sprayt of the machine on the plane indicated by troughs 30 suspended over the same cenline 2-2 in Fig. 1; Fig. 3, a cross-section trally thereof, the water being supplied to of a spray-trough in the machine, and Figs; said troughs through pipes 31. Each of the 5 4 and 5, similar views of shaking tables of spray-troughs herein shown has divergent the machine respectively indicated by lines and serrated sides and flanges, and the serra- 4-4 and 5-5 in Fig. 1; tions of the flanges break joints with those The framework of the herein described of the sides. The general construction of machine is of any suitable material and conthe s ray-troughs has particular reference struction, and as specified in my previous to a fine distribution of the water to have patent it preferably embodies, a primary the same fall in the grooves of the shakingcrusher, from which to feed crushed matables herein specified, said spray-trough terial to an elevator 14 from which it is dishaving been especially designed for that charged to tilt-sections 18 of the bed-box of purpose. a secondary crusher that also comprises a A driven crank-shaft 43 of the machine is rocker-block 19. Means for regulating the connected by a link 44 with a grid 45 supfeed and for operating the rocker-block, as ported on rollers 44', reciprocative motion well .as for alternate dumping of the tiltbeing imparted to said grid, and'said cranksections of said bed-box of the secondary shaft is provided with a cam-wheel 46 encrusher, are clearly shown and described in gaged by an arm 27 of the table 27 that is said previous patent. Material discharged in pivotal connection with said grid at 45', from each tilt-section of the aforesaid bedand is supported by rollers 45" thereon. box falls upon a vibratory screen 22, and the Hence it will be observed that the table has tailings from this screen have gravity decompound reciprocating and vibratory mo- 1 scent in a conductor 23 from which they tion. The other table 27' is also shown y be d back to the n ary llsherroller-supported on a grid to which it is piv- Like in said previous patent, the screen is otally connected at 45", this grid being provided with an arm 22' that engages a roller-supported similar to the one first cam-wheel 38 on a driven shaft '37, and aforesaid. The two grids as well as the two said screen has pivotal connection with a tables being coupled, as herein shown, they support 39 with which the frame of the have the same reciprocative and vibratory motion. The grids and tables may be indefinitely continued in the same manner as herein specified. The grooving of the shaking-table 27 is preferably such as is shown inFig. 1, there being a convergence of one series of grooves thereof to a single groove of another series, and from this groove of the second series, the material under treatment is flooded laterally to the other grooves in the same series, the ridges between grooves in said second series being beveled as shown in Fig. 4. The grooving of the shaking-table 27' is preferably that shown in Fig. 1, and for a portion of the length of this table, back of the settling-box 28, the ridges between grooves are beveled, as shown in Fig. 5, to permit lateral flooding of material under treatment from one to another of said grooves, the tailings finding their way from one of the aforesaidgrooves through a s out.27 to a compartment of said settlingox, as shown in said Fig. 1.

I claim 1. In a separator, the combination of a 5 primary splrally grooved shaking-table, there being a first series of spiral grooves in said table converging to a single groove in a second series of similar grooves and a beveling of ridges between the grooves of the second series to provide for lateral flooding of the material under treatment'from groove to groove; and means'for spraying water on the table.

2. In a separator, awater-spraying trough having divergent serrated sides and flanges, the serrations ofthe flanges breaking joints with those of the sides. v

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee 40 I in the county of Milwaukee and State of Wisconsin in the presence of two witnesses. THEODOR' VVILLMA. Witnesses: 7
